Developed for dissolved oxygen and temperature measurement in water, wastewater, analysis, allows compensation for altitude and salinity.

Versatile, water resistant multi-parameter portable meter, large LCD that clearly displays the parameter being measured as well as calibration instructions.

Accurate & portable instrument for the determination of in-situ shear strength of cohesive soils, either in situ or on undisturbed samples in a laboratory.  The instrument consists of a torque head with direct reading scale which is turned manually. A non-return pointer indicates the reading. Vanes come in either 19mm or 33mm diameter covering a wide range of soil cohesiveness. 

High precision instrument with a solid-state sensor designed for flow measurements in open channels where fouling by weed or sewage can be a problem. This Valeport is fitted with a flat sensor head suitable for shallow flows or measurements in confined spaces. It can also be used in turbulent flows if a longer sampling period (> 30 secs) is used.  The Valeport flat type sensor has a range from -5 m/s to +5 m/s and is powered by 8x alkaline C cells for up to 37hrs operation.

Easy and reliable sound velocity casting with the rugged, stainless steel Digibar S, designed for un-tethered sound speed profiling.

Specialist grab for benthic sampling, area of 0.1m sq. The option of lead ballast weights. Manufactured in 316 stainless steel.

Grab for obtaining samples from sediment in water environments. Up to 20 cm deep samples of roughly 0.1 m² can be extracted. Light-weight and easy to use. Dimensions: 80x23 cm (set), 35x24 cm (sprung). Volume: 1.67 litres.

Grab for obtaining samples from soft, finely divided littoral bottom sediment. Manufactured in 316 stainless steel. Dimensions: 19.5 x 25 cm and 35 cm high.

For sampling to a depth of 5m. Possible applications: Environmental soil research, Undisturbed sampling, Sewage water research, Sludge sampling & Sediment sampling.

Used for obtaining disturbed soil samples at or near the surface and for boring to depths where samples may be obtained with a soil sampler or soil core sampler.

Modular HDPE pontoon, securely linked together using moulded plastic screw fittings. Rapid assembly to an infinite variety of shapes and great load capacity.

Ideal for sampling trace metals and for organic sampling to concentrations of mg/L. Made of materials that avoid contamination via leaching. The horizontal flow of water through is not hindered by constrictions. The sampler is also suitable for measuring parameters in water with particulates or constituents bound to them. The Van Dorn sampler has a 2.2L Volume capacity. 

Water level datalogger which automatically and continuously measures fluctuations in groundwater and surface water levels and temperature. Data logs are stored in the data logger’s memory and can be downloaded using the Solinst software (optical docking station required).  Readings can be compensated for atmospheric pressure with the Barologger Edge.  The levellogger can be used up to 5m depth.

The Barologger Edge measures and logs changes in atmospheric pressure, to compensate water level readings recorded by the Levellogger Edge. One Barologger can be used to compensate levelloggers in a 30km radius and/or with every 300m change in elevation. Typically deployed above high-water level in one location on site. The Levellogger Software Data Compensation Wizard, using the synchronized data files from both the Barologger and levellogger, can produce compensated data automatically.
